Double link chain. Red led light placed on the actuator to signal the close position.

Minimum window height: 900 mm for 450 mm stroke, 1200 mm for 600 mm stroke, 1600 mm for 800 mm stroke.

For windows without windowsill a fixing bracket (sliding within the dovetail slide) is available for an easy installation.
